' V This invention relates to concrete forms vandthe like'for building construction and concrete construction.

' Most forms for concrete in use today are of a more or less specific construction for specialjobs or particular purposes and are of special, unwieldy and heavy construction inutile for any type of construction other thanthat forwhich they have been designed specifically. Furthermore many of the prior forms for concrete construction being of spec'ial-shape are either non-adjustable to com pen'sate-fOrVaryiDg conditions, that is, are

not susceptible for varying the dimensions of the construction work to be done, or'involv'e; very complicated arrangementsto accomplish this end.

One" of the primary objects of my inventio'n'is to provide a concrete construction form of simple but rigid and rugged construction adapted tobe put to 'awide diversity of useswithout requiring the provision of specially formed members and one which islight in weight and'may be-easily and 'cheaply'manufactured and handled. In

thlSCOIlIlGCtlOl'l the invention contemplates a formthe component elements of which may be easily and quickly adjusted with respect to one another and with respect to the dimensions of 'thebuilding or other structure being formedwso that practically any desired size or shape in any of the dimensions may be quickly and simply eflected without special equipment, I c v Many further objects, as well as the ad- I vantages and uses of my inventiomwill be or should become readilyand quickly ap-' preciated after perusal of the following description'and claims and after viewing the drawings in which:

Fig. 1 is a sectional view of a concrete form constructed in accordance with and utilizing a preferred form element of my invention.

Fig. 2 is a sectional view taken along the line 2-2 of Fig. 1.

Fig. 3 is a vertical sectional view of a column form constructed in accordance with my,

invention.

Fig. 4 is a transversesectional view of such column. s Fig. 5 is a top plan view of a form element or member, and

Fig. 6 is a sectional view thereof taken on the line 66 of Fig.5.

Referring to the Figs. 1 and 2, in which a floor and beam construction is illustrated, and to Fig. 5. Suitable supporting framework including shoring 2 supporting temporary beams-3 and 4: supplemented by bracing members, such as braces 5, for long vertical walls.

and the like constitutes asuitable foundation for a construction of the character illustrated. The space 6 indicates the area to be filled with concrete, whether reinforced or not, to provide a concrete beam and is formed by overlapping angle plates or members 7 which may be of any desirable length and breadth of legs, although one of the legs 8 is preferably short and serves to space the long leg 9 at some reasonable distance from the formwork when abutting at their outer edges against battens 11, 12 and 18, which for the purpose are suitably supported by the foundation of the formwork at spaced intervals and extend in a direction transverse the length of the legs 8. For a beam construction the lowermost plate 7 is supported by the batten 12 and in spaced relation to the batten 11 by means of a longitudinal member or block 14 which is of sufficient thickness as to space the mould surface of the plate 7 substantially parallel to the surface of the bat ten 11. Nail holes 15 are punched through the long legs of each plate at predetermined intervals laterally and longitudinally in order that nails 16 may be driven through the openings or holes into the formwork for securing the plates in position. The lowermost plate is therefore secured to the blocks, battens 14 and the batten 5 by nails 16. The succeeding plate or member 7 has its long leg 9 overlapping the lowermost plate or member 7 at its side or edge supported by the short leg thereof and this overlap may be varied. as may be desirable, in some instances to such an extent that one or more of the holes 15 in-one plate or member will register with the holes 15 in the other plate or member so that a nail may be driven through the registered holes into the formwork. In other instances,the nails may be driven into the formwork through one plate only. In this manner the mould sides may be built up.

For the bottom of the mould, if at right angles to the sides, the'exteriorsurface of the short leg of one of'the plates or member 7 may be abutted against the exterior face of the long leg of one of the side elements and is secured in place thereagainst by nails 16 driven into the battens 12. In like manner the unsupported edge of one of the plate elements 7 .may be supported in perpendicular spaced relation to the battens 12 by one or .more blocks 17. When it is desired toconnect a floor to the beam the plates 7 are dis posed with their long legs horizontal or otherwiseas necessity arises and supported upon the top ends of the battens 13'and the side of a transverse member 18 secured to the battens and upon the foundation member 1, nails 16 being driven into the formwork wherever it may be necessary so to do. The ends of the plates 7 adjacent the beam may be abutted against the ends of the short legs and the top -members 7 of the beam. As shown supported on the member a in Fig. 1 each plate or mem .I have found it desirable to secure them to a transverse batten strip, such as that illustrated at 19; Laterally the platesoverlap, as shown in Fig. 2, and for the purpose of alignment or for other reasons which may arise in practice, I prefer to place longitudinal blocks or runners 21 at suitable intervals, lapping the long leg of a member 7 over each of them on one side and abutting the short leg 8 of a member 7 against them .on the other side. Utilizing the construction described itwill be appreciated that the walls or sides of a form may be constructed as units, each unit composed of several plates or members 7 and the units thereafter put in place.

In Figs. 3 and 4 the method of constructing a column in accordance with the invention as illustrated differs'very little from that previously described.v In this instance it may be preferable to construct each side A, B, C, V,

and D of the column as a unit, nailing the plates 7 to the battens 22 and 23 before the several units are secured together in column form. In this wise the units A and C and B and D may be made substantially identical construction. Where, the columns are of such length as to necessitate two or more plates arranged lengthwise, the top plate is always arranged tooverlap the lower plate with one another, greatly simplifying the V onthe inside of the mould and as shown in Fig. 3 this scheme may be easily carried out when the column is more than one plate width on a side. The corner constructionshown in Figs. 1, 3, and 4 is of particular importance since the battens 14 or, 24:,which extend longitudinally of the plates, together with a pair of plates having their long legs ,abuttingone another, and the battens 11, 12, and 13, or"

23, as the case may be, provide a very simple put peculiarly eflicacious corner mold or form. '7 I The form elements 7 are preferably made of sheet steel and need not be'of great weight, since the elements cooperate with one another 1 and with the formwork to provide a very" rigid and substantial structure. The plates may be punched with the openings 15 at any desirable intervals, or in any manner which necessity demands so that they may be overlapped laterally and longitudinally with one another to provide a form of any desirable width or length. Not only may the sidesof a column be made up ofpre-formed andindependent unitssecured together, but constructions such as those illustrated in Figs. 1 and 2 maybe likewisepre-formed in units and the units assembled after the formwork, that is, the foundation structures, have been erected. Utilizing constructions, such as I have provided by my invention, should efiect a material saving in labor and supporting framework over what is known and in use to day, as will be appreciated, and many other advantages'and novelties accruing with my invention should be apparent.

While Ihave shown and described'certain preferred forms 'of my invention and'have the angle thereof, the short legs being directed outwardly of the corner,a batten'extend ing longitudinally of said plates adjacent I I of said plates, and means securing said one plate to said batten.

' 2. A concrete form for corner construction comprising a pair of angle plates each having one long and one short leg, the long legs of the plates abutting one another throughout their lengths at the corner and defining the angle thereof, the short legs being directed outwardly of the corner, a batten extending longitudinally of said plates adjacent the juncture thereof at the exterior side of'the corner to brace the edge of the long leg of one of said plates, a second batten extending transversely of the other of said plates on the exterior side thereof, and means securing the .plates to their respective longitudinally and transversely extending battens.

In Witness of the foregoing I aflix my sig- 7 nature. c
